Remote Code Execution Issue in Sitecore Experience Manager and Experience Platform

CVE-2025-27218

What is CVE-2025-27218?

CVE-2025-27218 is a serious vulnerability affecting Sitecore Experience Manager and Experience Platform, specifically versions prior to KB1002844. This vulnerability arises from an issue of insecure deserialization, which could be exploited by attackers to execute remote code. Sitecore's tools are widely used for managing digital experiences, and a successful exploitation of this vulnerability could severely disrupt an organization's operations, leading to unauthorized control over sensitive systems and data.

Technical Details

The vulnerability is rooted in the way Sitecore XM and XP handle serialized data. Insecure deserialization can allow malicious actors to craft specific inputs that the system processes in an unsafe manner, leading to potential execution of arbitrary code on the server. This could compromise the integrity and availability of web applications built using these tools. The flaw underscores the importance of implementing robust serialization and deserialization practices to safeguard against such exploits.

Potential Impact of CVE-2025-27218

1. Unauthorized Access and Control: The vulnerability allows attackers to gain remote control of affected systems, which can lead to unauthorized access to sensitive information and manipulation of digital assets.

2. Data Breaches: Exploitation could result in significant data breaches, exposing user data and intellectual property, potentially leading to compliance violations and reputational damage.

3. Disruption of Services: Attackers exploiting CVE-2025-27218 can disrupt services provided by digital platforms, leading to downtime, financial losses, and erosion of customer trust.
